CLOSING DEVICE FOR SODA-WATER BOTTLES, 800.

SPECIFICATION forming part of Letters Patent No. 462,576, dated November 3, 1891.

- Application filed April 2, 1891. Serial No. 387,375. (No model.)

To all whom it may concern;

Be it known that I, J OHANN NADLER, me chanical engineer, subject of the Emperor of Austria, residing at Vienna, in the Province of Lower Austria, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Closing Devices for SodalVater Bottles and the Like and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains' to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The invention relates to that class of siphons more especially designed for use with bottles containing effervescent or gaseous liquids.

The invention has for its object to so construct the siphon that ready access may be had to all of its parts, and to admit in its construction of the use of materials not affected by the liquid.

The invention consists in structural featu'res and combinations of parts, as will now be fully described, reference being had to the accompanying drawings, in which Figures 1 and 2 are vertical sectional elevations of the siphon, illustrating its application to a bottle, the valve in Fig. 1 being shown on its seat to close the outlet, while said valve is shown off its seat in Fig. 2 for filling the bottle or dispensing its contents. Fig. 3 and 4: are sections taken, respectively, on lines was and y yof Fig. 1. Fig. 5 is aperspective view of the valve; and Fig. 6 is a perspective view of the plug that supports the siphon-tube.

In the above drawings, A indicates the barrel of the siphon, provided with the filling and discharge nozzle a, which communicates with a contracted portion of the bore of said barrel. On opposite ends of said contracted portion 0 the bore of the barrel is enlarged to form two chambers c and 0 the lower chamber 0 being the valve-chamber, and having its lower end closed by a plug E, hereinafter to be described, while the upper chamber serves for the reception of a pushbutton C, that has a throat 0, into which projects a pin 0 secured to the barrel, which pin serves to limit the motion of the button in either direction. The button 0 has a stem 0 that extends into the contracted portion 0 of the bore to near its lower end, around which lower end is formed the seat for a valve. The stem 0 of the button C carries an elastic sleeve d, that abuts against the button and against the floor of its chamber 0 around the bore to form a fluid-tight joint. It is evident that when the button is depressed the elastic sleeve (1 will be compressed, expanding around the stem and the bore 0 to more effectually seal the same.

To prevent too great compression of the sleeve d, I preferably employ a bracin '-slee"e (Z shorter than sleeve (1, to admit of a suitable compression of the latter and proper movement of the button in unseating the valve. The elastic sleeve (l also acts as a spring on the button and moves or assists to move the same back into its normal position when moved out of it.

As shown in Figs. 2 and 3, the contracted portion c of the bore of the barrel is made to taper upwardly, its least diameter being at the point where it opens into the chamber 0, while its greatest'diameter is at apoint where it opens into thevalve-chamber c and at which point is formed the seat for the valve 13. This construction not only affords free passage to the liquid from the valve-chamber to the dis charge-spout or from the latter to the valvechamber, but also facilitates the packing of the upper end of the bore, which is very eifectually done by the means above described.

The valve 13, as shown in Figs. 1, 2, and 5, is a cylindrical gravity-valve of such diameter as to fit the cylindrical valve-chamber c snugly, so as to be properly guided to and from its seat. To afford free passage to the liquid around the valve when off its seat and to the tapering bore 0 of the barrel, the periphery of said valve is ribbed or corrugated vertically, as shown at b. This, however, is not absolutely necessary, as other means may be adopted to afford passage to the liquid either around or through the valve. The valve-chamber may, for instance, be made square in cross-section, and a cylindrical valve having a smooth periphery employed, said valve being of substantially the same diameteras the chamber, so as to be properly guided in its movements to and from its seat. The

valve B may also be provided with passages leading from the lower face thereof to its upper peripheral edge or face or with a spiral peripheral passage or groove.

In its under side the barrelA has an annu lar recess that forms a seat for the circular flange e of the plug E, that serves to close the lower end of the valve-chamber in which plug the siphon-tube ais secured. To prevent the valve B from closing the bore of the plug and thus prevent access of liquid to the bottle, said plug has on its upper face around the bore four (more or less) pillars e, forming passages for the liquid between them when the valve B seats thereon in filling the bottle F. In the application of the siphon to the bottle F a gasket of rubber is first applied around the mouth of said bottle, a clampingsleeve G is next slipped over the neck. The plug E is then inserted into said neck with its annular flange 6 bearing on the gasket. The barrel A is now seated on the gasket and on said flange e of the plug E and is secured in position by a sleeve G, constructed in two parts, over which the clamping-sleeve G is slipped. The upper and lower edges of the two-part sleeve G are then respectively bent under the head of the neck of the bottle and into the annular groove a -of the barrel, thusfirmly securing said barrel to the bottle, as shown in Fig. Y

It will be observed that the plug E below its seat-flange is of slightly less diameter than the mouth of the bottle, and that the opening in the gasket f is also of less diameter than the said mouth of the bottle, so that when said plug is inserted the edges of the gasket around its central opening will be forced inwardly and downwardly to form a fluid-tight oin Instead of the means just described for attaching the siphon to the bottle, said siphon may be secured to the bottle by means of cement, as shown in Fig. 2, the barrel A having its lower portion a chambered to receive the mouth of the bottle and the lower edge of said chambered portion bent inwardly to form an annular locking-flange for the cement. As constructed, the'barrel of the siphon, as well as the push-button, the valve,and the 'plug, can be constructed of such materials as will not be acted upon by the effervescent or gaseous contents of the bottle.

The barrel, the valve, the push-button, the plug E, tube a, and brace-sleeve (1 maybe made of glass, or either or all of them may be made of hard rubber or other material of a like nature; or said brace-sleeve d, as Well as the clamping-sleeve G, may be made of 1 metal, as well as the two-part sleeve G, and

the metal for the latter should be sufficiently ductile or pl able to have its edges readily bent inwardly, for the purpose set forth.

The construction and combination of the co-operative parts of the siphon, as described, permit its ready dismemberment and admit of free access to the fluid-passages for the purposes of cleansing.

Having thus described my invention, what I claim is 1. A fluid-discharging device comprising a barrel a portion of whose axial bore is contracted to form a valve-chamber on one side and a chamber for a push-rod on the opposite side of such contracted portion, said barrel having a discharge-nozzle leading to said contracted portion ofthe bore, said parts forming an integral whole, in combination with a gravity-valve contained in said valve chamber, a push-rod located in the opposite chamber and extending into the contracted portion of the bore, said push-rod being provided with an abutment, an elastic sleeve on said rod between the abutment and the contracted portion of the axial bore, said sleeve operating as a packing for said contracted portion of the bore and the push-rod and also as an actuating device for said rod, and a stop operating-to limit the expansion of the sleeve, for the purpose set forth.

2. In a siphon of the class described, the combination, with a bottle and the barrel A, provided in its under side with an annular recess formed around its bore, and the plug E, provided with an annular flange adapted to seat in said recess, said plug carrying the siphon-tube, of a packing interposed between the barrel and the plug E and the mouth of the bottle, a two-part sleeve G, encompassing the lower end of said barrel and the mouth of the bottle, and a clamping-sleeve G, encompassing said tw'o-part sleeve, for the purpose set forth.

In a siphon of the class described, the combination, with the barrel A, having the tapering axial bore 0 and the chambers c c at opposite ends thereof, of the valve B, the push-button 0, having stem 0 and throat c, the elastic sleeve d and bracing-sleeve d,.surrounding the same on said stem, and the pin 0 projectinginto said throat c, said parts being arranged for operation as and for the purposes set forth.

In testimony whereof I affix my signature in presence of two witnesses.

I JOHANN NADLER.
